How automatic failover actually works

📡

Primary line drops

FTTC, FTTP or leased line goes down — could be a BT outage, builder’s spade, or DSLAM reboot.

⏱️

Router detects in 5–15s

Failover router pings a target (8.8.8.8) every few seconds. Three failed pings = WAN down.

🔄

4G/5G takes over

Router brings up the 4G/5G interface, advertises new default route, NAT continues.

✅

Users barely notice

Live calls may drop briefly; web sessions resume on next request. Average outage to user: 20–40 seconds.

When 4G/5G failover is essential

You take card payments — every minute offline = lost revenue. Pays for itself in one Saturday.
You run hosted VoIP — failover keeps phones working through fixed-line outages.
You use cloud-only software (Xero, Salesforce, M365) — staff can’t work offline.
You have remote sensors / IoT / CCTV — devices keep transmitting through fibre cuts.
You’re in a single-line postcode — no second physical line means failover IS the resilience.
You signed an SLA with your customer — most enterprise SLAs require redundant connectivity.

EE Business mobile backup — FAQs
4G/5G failover is even cheaper when bundled with the team’s existing mobile lines. Pair this with the best business mobile phone plans in the UK for combined network and failover savings.

Most cases yes — EE supplies a standard data SIM that works in any unlocked 4G/5G router (Cradlepoint, Teltonika, Cisco, Peplink). The pre-configured EE router just makes failover one-touch.

Not by default — failover changes your public IP. To keep VoIP registered through failover, use SIP over TLS with TCP keepalives (every modern hosted VoIP supports this).

Yes — Cradlepoint NetCloud and Teltonika RMS both push email/Slack alerts when failover triggers. Critical for tracking how often you’re actually using the backup.

Backup-only plans have caps (100 GB to 1 TB/mo). Standalone primary plans are unlimited but with fair-use throttling above 1 TB. For an office of 10 staff working 8 hours on a fixed-line outage, expect ~20 GB used.
